BIRDS!

@birdingnut more specific please.

@Unclehotrod A couple of weeks ago, I saw a greater roadrunner run down and rip the intestines out of a desert cottontail, then run off with pink intestines streaming out behind it.

@birdingnut I'm not a an expert on birds, but are there any left from the mesozoic era?

Brontosaurus, and Fred Flintstone loved their ribs!

@Unclehotrod I'm not sure what you're asking, but all birds came from dinosaurs.
Unless you are asking about birds that look prehistoric, like hoatzin chicks, that have claws on their wings for climbing through mangrove swamps.
